Application fi1ed November 14, 1927. Serial No. 233,134.

This invention relates to kitchen articles, and more'especially toastirrer of t-hetype used for light mixing and beating in the culinaryart.

An object is the provision of an improved stirrer or beater capable ofmore quickly and thoroughly performing its function such as mixingmayonnaise, beatin g eggs, ping cream. V I

With the foregoing and other objects in view which will be madeinanifestin the following detailed description and specifically. pointed out inthe appended clain'is, reference is had to the QCCOl'flPltnylIlg drawi sfor an illustrative embodiment of the invention,.wherein: I p

Figure 1 is a front elevation of .the improved stirrer of iny invention.

Fig. 2 is a side elevation of the stirrer of Figure 1.

Fig. 3 is a horizontal sectional view of the stirrer, the plane ofsection being indicated by the line 33 of Figure 2.

Referring to the accompanying drawings wherein similar referencecharacters designate 'milar parts throughout, the preferred embodimentof my improved stirrer comprises a head 1, to which is rigidly secured,a handle A et-shaped frame 3 is extended dmrnwards from the bottom ofthe head 1, and. the lower end of the frame 3 is extended or whipin theform of a hollow circle 4, the bottom 6 of which is substantiallystraight and connected to the circle 4 by a pair of spaced verticalsections 7 to provide journals. li lounted for rotation upon each of thelegs of the U-shaped frame 8, is aU- shaped stirring element 8; and thebottom of eaehof l'he elements 8 is extended to provide a paddle 9 inthe form of a hollow circle. The bottom 11 of each of the paddles 9 isjournaled upon one of the vertical sections 7 of the frame 3.

Each stirring element 8 is provided at its.

jacent each other, and are so positioned that when rotated, each side ofeach of the paddles 9 intersects the plane of the other paddle 9 as bestshown in Figures 1 and 3. The arrangement of the gears 12is such thatwhen rotated by the larger gear 13, the stirring ole ments 8. will; berevolved inopposite direc- LlOnS.

The structure so far described is that of i the well known egg-beater,and no claim The improvement of 'my .in-'

made thereto. vention however, comprises i roviding a plurality of m.ing blades 16 and 1'? upon the upper and. lower parts respectively,ofeach of the paddles 9. The lower bladesl'? are arranged withjtheirleading edges inclined downwards so that as they are rotated in a fluid,the fluid engagedthereby is directed npwards; and the upper blades-16arealranged with their leading edges inclined upwards so that fluid.engaged by the blades 16 is directed downwards It is thus seen'that avery quick and thorough mixing may be effected by the use of my improvedstirrer. The two fluid streams, one

bein directed u wards from the lower blades 17 and the other beingdirected downwards from the upper blades 16, being forced tointer-mingle somewhere within the confines of the path of travel of thepaddles 9, and then thoroughly broken up as they emerge paddles 9between the blades 16 and 17.

While my invention has been described as having circular paddles, it isto be understood that I do not wish to limit myself to this form. ofpaddle. The essential feature of my invention is a pair of. rotatablemixing blade-s, disposed one above the other, the upper blade beingadapted to direct the material being stirred downwards, and the lowerblade being adapted to direct the material upwards. A s

It will be understood that various changes in the details ofconstruction may be made without departing from the spirit or scope ofthe invention as defined by the appended claims. p

.I claim:

1. A stirrer comprising a frame, a stirring element journaled thereon, apaddle in the form of a holloweircle carried by said stir ring element,a blade arranged on the lower part of said paddle,with its leading edgeinclined downwards, a blade arranged on the upper part of said paddle,with its leading edge inclined upwards, means for rotating said stirringelement and a blade connecting said inclined blades and disposed withthe plane thereof substantially at a tangent to the line of rotation ofthe paddle.

2. A stirrer comprising a frame, a plural between the straight sections18 of the paddle.

ity of stirring elements journaled thereon, a

paddle in the form of a hollow circle carried by each of said stirringelements, a blade arranged on the lower part of each of said paddles,with its leading edge inclined clown- Wards, a blade arranged on theupper part of each of saidpaddles, with its leading edge iclinedupwards, means for rotatlng said stirring elements and a bla dec-onnecting each pair of said inclined blades and disposed with theplane thereof substantially at a tangent to the line of rotation of theassociated each pair of said inclined blades and disposed with the planethereof substantially at a'tan" gent to the line of rotation of theassociated paddle.

4. A stirrer comprisinga U-shaped frame extended at its lower end intothe form of a hollow circle, a pair of U-shaped stirring elementsjournaled on the respective legs of said frame and geared together forrotation in 0pposite directions, eaclrof said elements being' extendedat its lower end'to provide a paddle in the form of a hollow circle,said elements being arranged closely adjacent each other for theirpaddles to rotate freely within the circular part of the frame, and foreach side of each of the paddles to intersectthe plane of the otherpaddle once during eachrevolntron thereof, blades arranged on the lowerpart of each of said paddles, with their leading edges inclineddownwards,v

blades arranged on the upper partofeach of said paddles,'witli theirleadin edges in clined upwards, means for rotating said'stirringelements and a blade connecting each pair of said inclined blades anddisposed with the plane thereof substantially at a tangent to the lineof rotation of the associated paddle.

In testimony whereof I havesigned my name to this specification.

RICHARD C. GOODELL.
